I do not wear contacts and I have had a horizontal line/vein, which is very noticeable, going from the inside of my right eye towards the iris. it is almost touching the iris actually. it has been there for almost a year now and i would like to know what it is and how to get rid of it. by the way, i do a lot of work on computers (most of my day consists of computer work.) could that be why? help me out!
